Hi. Apparently there's something wrong with my circuit and I can't figure out what they are. The output file said that some of the nodes are floating. Don't really get this.
Here is the schematic.


Thanks.
 

Dear Friend
Hi
I don't think that your circuit has problem . it is correct. your edit simulation has problem , i think.

I don't know about floating nodes, but it won't like C3 - it will produce infinite current on switch on. You may as well remove it as it is across a battery with zero series resistance anyway, or add some series resistance to Vdc.

You are right, C3 is not necessary at all as it has zero ohms in parallel - however, I do not expect any problems because of C3, neither in ac nor in transient analyses.
As indicated by kerim, the circuit is OK for simulation.
